IGF-1 LR3 in brief

IGF-1 LR3 comes in 2 strengths, 0.1mg and 1mg per vial, each a sealed box of ten: IG1 at $204.64 by the single box, IG01 at $31.16 in 50-box lots.

Nothing is on the shelf today. IG1 is made to order, about four weeks, in any quantity. IG01 is special order: brought in on a 50-box minimum rather than held in stock; ask the desk for the date before ordering.

What IGF-1 LR3 is

IGF-1 LR3 is a recombinant analogue of human insulin-like growth factor 1: the 70-residue hormone with arginine in place of glutamate at position 3 and a 13-residue extension at the N-terminus, making 83 residues in all, with the three disulfide bridges of the parent. Average mass 9111.6 with the bridges formed. It is expressed in E. coli and refolded, not synthesised on resin.

Its certificate reports purity by reverse-phase HPLC against the limit it states, identity by the method it names, endotoxin and the net content; misfolded and reduced forms are the related substances to ask the desk about. It carries three methionines, two in the extension and the one of IGF-1 itself, so an aged batch can carry their sulfoxides. Store frozen; avoid freeze-thaw.

Registry and identity

  • Long-(Arg3)insulin-like growth factor-I is the name FDA's GSRS gives this protein, with IGF-1 LR3 and Long R3 insulin-like growth factor-I as synonyms, under UNII M9L22Y19H9 and CAS 143045-27-6. FDA GSRS
  • GSRS's index name describes the 13-residue N-terminal extension, MFPAMPLSSLFVN, as residues 1 to 13 of porcine growth hormone with methionine at 1 and valine at 12, fused to human IGF-I that carries arginine at its position 3. FDA GSRS
  • The 70 IGF-I residues match the mature chain of UniProt P05019 (precursor 49 to 118) except glutamate 3, precursor position 51, which becomes arginine, and the three disulfides UniProt gives at 54 to 96, 66 to 109 and 95 to 100 sit at 19 to 61, 31 to 74 and 60 to 65 of the 83-residue LR3 chain. UniProt, FDA GSRS
  • Worked from the GSRS sequence with its three disulfides, C400H619N111O115S9, and NIST isotope masses, the monoisotopic mass is 9105.349, so the monoisotopic 7+ ion is at m/z 1301.771. FDA GSRS, NIST

A listing in these registers identifies a substance; it is not an approval of this line.

IGF-1 LR3 beside IGF-DES and CJC-1295

IGF-1 LR3 works out at $20.464 per mg at 1mg (IG1), its lowest by the single box. Its neighbours, on price alone: IGF-DES at $1.558 per mg at 2mg (IGD, in 50-box lots), 7,365.4 g/mol, set side by side in IGF-1 LR3 vs IGF-DES; CJC-1295 at $1.042 per mg at 10mg (CP10), 3,647.3 g/mol.

Reading an IGF-1 LR3 certificate of analysis (COA)

Identity. Against the reference standard by the method the batch certificate names.

  • Where the certificate identifies by mass: three disulfides intact: mass six units below the fully reduced chain.
  • Endotoxin line present, as for any E. coli product.

Worked out from what the sheet holds for this line; the batch certificate is the record. How to read one, and verify a batch number.

Buy IGF-1 LR3 in bulk

IGF-1 LR3 is sold in bulk by the sealed box of ten vials, and every account starts at list price. Two discounts can lower it, the size of one order (from $5,000 of goods) or the account’s tier (from lifetime paid spend), and the better one applies, never both. Priced below on IG1, 1mg x 10 vials, the best-priced strength.

Questions about IGF-1 LR3

Which IGF-1 positions do the three disulfides of IGF-1 LR3 join?

In the 70-residue hormone its three bridges join cysteine 6 with 48, 18 with 61, 47 with 52. The 13-residue extension in front moves every IGF-1 number up by 13 along LR3’s own 83, giving 19 with 61, 31 with 74, 60 with 65; UniProt’s precursor, in which mature IGF-1 begins at 49, counts 48 higher, giving 54 with 96, 66 with 109, 95 with 100. IGF-1’s cysteines 47 and 48 stand side by side in different bridges, and the arginine replacing glutamate 3 is LR3’s residue 16.

How much does IGF-1 LR3 cost?

From $204.64 a sealed box of 10 vials, which works out at $20.464 per mg at its best-priced size. IG01 is special order, 50 boxes at least, at $31.16 a box. To a US address, freight is included from $1,000 of goods; below that it is the carrier’s rate for the carton or a flat $35.00, and to another country the desk quotes it; either way the figure is on the proforma before you pay. Every strength and its price per vial is in this page’s price table.

Which IGF-1 LR3 size is cheapest per mg?

IG1, 1mg x 10 vials, at $20.464 per mg.

Can I buy a single vial of IGF-1 LR3?

No. One sealed box of ten vials is the smallest quantity of a regular line; for IGF-1 LR3 that is IG1, 1mg x 10 vials, at $204.64. A first order must reach $100 of goods, which one box of IG1 clears. IG01 is special order and takes a minimum of 50 boxes. A box is sealed at fill with its batch number on it, and splitting one would break the link between the vials and their certificate.

Which IGF-1 LR3 strengths are in stock today?

None today. IG1 is made to order, about four weeks, in any quantity. IG01 is special order: brought in on a 50-box minimum rather than held in stock; ask the desk for the date before ordering.

How is IGF-1 LR3 stored?

At minus 20 degrees Celsius, dark and dry. Lyophilised powder tolerates a short spell at ambient temperature in transit, which is why boxes ship without ice. Storage and handling.

What is in a box of IGF-1 LR3?

Ten sealed vials of one strength, each labelled with the product code, the strength and the batch number; the trade also calls a box a 10-vial kit. IGF-1 LR3 is supplied as a powder in a sealed glass vial and in no other presentation. Boxes are not split.

Is a certificate of analysis (COA) provided for IGF-1 LR3?

Yes. For IGF-1 LR3 the batch certificate reports its purity by reverse-phase HPLC against the limit it states, its identity by the method it names, endotoxin and its net content. The other lines on this page are the specification it is made to, and the desk answers for them on a particular batch. The certificate is sent with the shipment, and again on request, and any batch number can be verified on the certificate page.

Is this for human use?

No. Everything here is supplied for laboratory research only, to trade accounts, and is not for human or animal consumption. The research-use page sets out who can buy and what is not sold.
